Re: Lowe's
Plan Review of 40% Submittal
BRA File No. 55-05-000
Dear Eric:

Traffic/Site Layout
West Highway 36 St. Paul, MN 55113
Office: 651 • Fax: 651
We have reviewed the preliminary plans and Traffic Report for the proposed Lowe's as
submitted, on January 11, 2005, by Ozark Civil Engineering, Inc. Following are our
comments and/or recommendations.
• St. Paul, St. Cloud, Rochester, Willmar, MN • Milwaukee, W1 • Chicago, IL
Affirmative Action/Equal Opportunity Employer and Employee Owned
1. It is recommended the entrance on Memorial Avenue be widened a minimum
of 10 feet. With the wider entrance the trucks leaving the property will still
turn into the southbound lane on Memorial Avenue, however, they will be
able to make the right turn without driving over the curb.
2. it is recommended that the south radius at 58 and Memorial Avenue be
increased from 42 feet to 60 feet. Even with the larger radius, trucks turning
right from Memorial to 58 will need to drive into the west bound lane on 58
Street; however they will be able to remain on the pavement.
3. Revisions will be required on the traffic signal and loop detectors at Highway
5 and 58 Street. MNDOT will need to review and approve these revisions.
4. It is recommended that 58 Street be widened to four lanes from Highway 5
to Morning Dove Avenue and then taper back to the existing two lanes on the
west side of Morning Dove.
5. The south entrance on Morning Dove Avenue should be reconfigured to
reduce the number of movements at this intersection. It is recommended that
a canoe be placed to force entering traffic to make a right or left turn. This
will reduce the number of parking stalls; however, it will improve operation
and safety. See the attached Figure.
6. The north entrance on Morning Dove is to close to 58 Street. This entrance
should be reconfigured to allow incoming traffic only.
MNDOT Issues
1. The developer should contact MNDOT on the following issues:
a. Setbacks from MNDOT's right-of-way for proposed improvements.
Storm Sewer and Ponding
b. Modifications to 58 Street at Highway 5 within MNDOT's right -or-
way.
c. As stated above, any signal modifications at 58 Street N. and
Highway 5.
1. Provide storm sewer sizing calculations.
2. The Brown's Creek Watershed District and the City of Oak Park Heights
approved the previous grading plan and proposed storm water ponding and
calculations for this area by the previous owner, as such, the storm water pond
in the southwest corner along Memorial Avenue can be reconfigured;
however, the storage capacity must be maintained.
3. It is possible to combine the storm sewer system on the south side of the
building to reduce the number of FES discharging into the pond?
4. To prevent erosion it is recommended that rip rap be placed at all flared end
sections that discharge into the pond.
5. The storm water management report has been submitted and will be reviewed.
Water Main
1. The proposed connection to the existing water main is currently shown within
Memorial Avenue. It is recommended that the water main be looped with a
connection to the existing 8" main on Morning Dove Avenue.
2. The first note on the utility sheet states that the water main shall have 3' -6" of
cover on top of pipe. This note should be changed to read 7'-6" of cover
above the top of the pipe.
3. Proposed fire hydrant shall incorporate an AFC - Waterous Storz Nozzle. The
hydrant pumper nozzle shall be of one-piece design, compatible with a 5"
Storz hose coupling. The nozzle shall be an integral part of the fire hydrant
and must be furnished by the manufacturer or authorized distributor
designated by the manufacturer. Storz adapters will not be accepted.
Sanitary Sewer
1. The second note on the utility plan states that the sanitary sewer shall have a
minimum cover of 3.0' above top of pipe. This depth should be changed to
6.0'.
2. Note 22 on the utility sheet states that the top of any manhole in a grassy area
shall be 6" above grade. This should be changed to place the cover at grade.
If the manhole is in a drainage swale /ditch a watertight casting shall be used.
General Comments
1. Several notes on the utility sheet reference details. All these details should be
submitted for review.
2. A detailed sediment and erosion control plan needs to be included as part of
the general plan submittal, as it pertains to the grading and private storm
sewer construction activities.
The above comments are related to the 40% plan submittal. As the plans develop,
additional reviews will be required If you have any questions or require additional
information, please contact me at (651) 604-4788 or Dennis Postler at (651) 604 -4815.
